Super Time Force Ultra is coming to Steam on August 25th, and it’s bringing along three new friends that should be a little familiar…

We’re ULTRA excited to give Steam players a chance to travel through time with some of their favorite Team Fortress 2 and Left 4 Dead characters! Let’s take a look:

Light’em up! Pyro from Team Fortress 2 dials the heat to 11, then rewinds and dials it to 12. Destroy evil robots with the flare gun, or roast them good with the patented Pyro flame thrower.

She’s got two pistols and an endless supply of propane tanks. Zoey from Left 4 Dead has taken a break from slaying zombies to hop through time with the Super Time Force! Blast baddies with twin handguns, or lob an explosive propane tank their way for maximum ‘splodiness.

When he’s not jumping from planes without a chute, wrastling gators, or beating up hippies, Team Fortress 2′s Saxton Hale tags along as the Super Time Force’s resident brawler/business man. Saxton uses his massive muscles, bare knuckles and self-confidence to smash Blounbot’s into a metal pulp. Then he rewinds and does it again.

All three Valve characters, along with 50 new Helladeck challenge levels and the new Ultra Force power mode are available in Super Time Force Ultra for $14.99 when it launches on Steam August 25th.

Want to see theses new characters, plus the other new STFU features in action? Head over to CAPY’S TWITCH and watch the crew livestream all this amazing stuff later today.

STFU brings all the insane time-travel action of Super Time Force to PC along with brand new bonus content including: 50 new Helladeck challenge levels, inter-dimensional Ultra Force powers and 3 super-awesome, super-secret new characters! STFU is the ultimate in personal computing time travel technology!
